1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

We present a high-resolution spatial dataset delineating individual rural household courtyards and building rooftops in a representative region of northern China, extracted from sub-meter remote sensing imagery using deep learning techniques. This dataset captures the fine-scale layout of rural homestead compounds, including courtyard boundaries and rooftop footprints, with high accuracy validated against field observations. The data were generated by applying convolutional neural network models to high-resolution aerial imagery, enabling automated identification of residential courtyards and associated structures over large areas. The resulting dataset provides unprecedented detail on rural settlement structure, which can be used to analyze food-energy-water systems and support sustainable rural development. For example, the rooftop layer can inform solar photovoltaic potential assessments and infrastructure planning, while the courtyard layer yields insights into household-level agricultural practices and land management. By filling a critical gap in micro-scale rural data, this openly available dataset offers significant value for researchers and policymakers focused on rural revitalization, resource management, and environmental planning.
